Comet 226P/Pigott-LINEAR-Kowalski. Exposure: 20x30s. Date: 2016 October at 04:45 EDT (midpoint). The faintness of the comet made stacking somewhat problematic (hence the slight curve to the star trails). Stacking on the stars (with the comet trailed) looks nicer. The comet was 2½° N of M1 at the time.
